Dont know what really happen. All I knew was that I the MAP sensor went bad and I had to replace it. Keep in mind that my car is 2000 and the sensors should not be going out this soon unless something caused it. That is why I think the ECU must have did something to make my Sensors go bad on me.
I think I will clean IAC next before I buy one. Thanks

Where are you pulling power and ground for the wbo2?? IIRC there are several people over on the aem forum that have had issues with the FJO setups causing readings to go whacky when using power directly from the ecu sensor feeds.
Also did you update the o2 maps for the AEM when you installed the sensor? If you had feedback on with the narrowband voltage settings it would _definitely_ idle funky.
